Passing arrays
How could I do the following:
I set the array size and contents in somefunc() and the return the array to the main.Code:int[] somefunc(); int main(void){ int i; int array = somefunc(); for(i=0; i<10; i++) printf("%d\n", array[i]); } int[] somefunc() { int size = 10, i; int array[size]; for(i=0; i<size; i++) array[i] = i; return array; }
The word you're wanting to search for is 'dynamic'.Code:int *somefunc( ... ) { int *notreallyanarray = malloc( sizeof *notreallyanarray * sizeyouwant ); ... return notreallyanarray; }
Quzah.
Hope is the first step on the road to disappointment.
But like how do you return it to the main which doesn't know the size?
I just showed you how. The size however isn't able to be determined with just a pointer alone. You will need to keep track of that on your own.
